PROBLEM TO BE SOLVED: To provide a component mounting device and a component position correcting method in a component mounting device that can enhance the mounting precision by miniaturizing an imaging unit.SOLUTION: An imaging unit 13 that images a component 4 from the lower side and images a target site 3d from the upper side while the component 4 held by a mount head 12 is located at a pre-mounting position above the target site 3d achieves an image (first image GZ1) of the component 4 obtained through an upper window 13J, and an image (second image GZ2) of a board 3 obtained through a lower window 13K as individual single images which are not overlapped with each other. A correction value calculator that calculates a correction value for positioning the board 3 and the component 4 on the basis of the images of the component 4 and the target site 3d which are obtained by the imaging operation of the imaging unit 13 compares the first image GZ1 and the second image GZ2, and calculates the correction value on the basis of the comparison result.SELECTED DRAWING: Figure 11 |
